ROLLER-SEAT FOR LATERAL-MOTION TRUCKS.

incassi.

To all whom it may concern.' l

Be it known that we, EDWIN W. WEBB and F RANKLIN L. BARBER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and .useful Improvements in Roller-Seats for Lateral-Motion Trucks; and we do hereby declare the following to be a full, clear,` and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to lateral motion trucks of the well known Barber type, and has for its object to provide an improved roller seat therefor. These roller seats are sometimes designated as combined spring caps and roller bases. A roller seat of this character is, for example, illustrated in thev J. C. Barber Patent No. 565,421, of date, August 11th, 1896, wherein the vertically movable elements illustrated in Figs. 5 and 6 of the said patent are guided for vertical movements by the bolster columns, and are termed spring caps, although they serve as combined spring caps and roller seats. 1n this specification, the said elements willw be designated as roller seats. n Roller seats of this character are notched, or otherwise formed so that they are provided with thrust lugs that engage the inner and outer sides of the bolster columns. These thrust lugs hold the roller seats against movements transversely of the truck, andare subjected to very considerable strains, due to the lateral movements of the car body in respect to the truck frames, so that, in practice, the said lugs have very frequently been broken oil". Our present inventiony affords a light, simple and strong construction'of roller seat wherein the lugs thereof are made strongI enough to resist the greatest strains to which they will ever be subjected in service.

Theimproved roller seat isillustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan view of the improved roller seat; Fig. 2 is an edge elevation thereof, showing the Specification of Letters Patent. i Pwbgmbd NUV 239191,60 Application filed September 3, 1915. Serial No. 48,929.

roller seat, however, turned into a vertical plane; Fig. 3 is a. vertical section taken on the line w3 m3 of Fig. 1; Fig. 4 is a side eleva.- tion of the improved roller seat; Fig. 5 is a bottom plan view of the same; and Fig. 6 is a vertical section taken on the line m6 m6 of Fig. 5.

The body of the roller seat is indicated by the numeral 1, and on its top it is formed with diverging roller bearing surfaces 2 and with raised stop flanges 3 at the ends of the said roller bearing surfaces, which latter prevent lendwise displacement of the rollers, not shown. At its ends, the body 1 of the saidseat is formed with large notches 4 adapted to embrace the bolster columns of the truck side frames. Otherwise stated,

the said roller seat -is formed at its ends with projecting thrust lugs 5 that engage the inner and outer faces of the bolster column. 0n its upper face the said roller seat 1 is formed with raised anges Gthat follow the three sides of the notches 4, and hence, extend along the inner upper portions of the said lugs 5 and on its under face, the said seat 1 is formed with corresponding depend# ing flanges 7 that follow or form continuations of said raised flanges 6, so that the flanges 6 and 7 very greatly afford vertically extended wearing surfaces for engagement with the truck bolsters. On its under side, the said roller seat l is further formed with depending flanges 8 that follow vthe inner and outer edges thereof, and also follow the eXtreme outer edges of the thrust lugs 5 and join integrally with the eXtrem-ities of the depending flanges 7. .This gives a very light and strong construction and carries the reinforcement tothe 'very ends of the thrust lugs 5.

A roller seat construction, as described, is well adapted to be made out of malleable casting, steel casting, or drop forging.

What we claim is:

A roller seat, for the lateral motion device of a car truck, formed on one face with roller bearing surfaces and providedat its ends with column-engaging notches, and thrust lugs at the extremities of said notches,

said seat, on its side with the roller bearing surfaces, having anges that .follow the In testimonywheieof we aix Our signathree sides Of said column-engaging notches tures in presence of two witnesses. anti On its other side having an endless Inar- EDWIN W. WEBB.
